No, I'm doing the original 1987 PC Elite. The later one was written by Chris Sawyer. I asked him recently and he also has no idea about Andy who wrote the prior version (both for Realtime).

It one-shot an entire filled poly renderer and 3D engine.
I worked with some of the original XCOM guys after a bunch of them left Microprose to set up on their own. I wrote a lot of the graphics engine for this, which was really a direct descendent of XCOM:
